Corresponding and like partsare referred to in the following descriptionand indicated in all the views of the drawing by the same referencecharacters.

The power to operate themachine may be supplied from any suitable sourceand is transmitted to the machine by a main shaft 1 on which are fastand loose pulleys 2, said shaft being journaled .in a post or standard 3of a supporting framework which may be of any desired construction ortype, just so long as it can support and house the actuating elements ofthe apparatus, said framework including in the present instance afoundation 4 and a cylindrical base 5 con,

nected to or formed integral with the foundation. The inner end of thedriving or main shaft 1 preferably has a clutch connection 6 with ashaft 7 that carriesa spur gear -wheel 8, the latter meshing with acorresponding wheel 9 movable wit-h anddriving a stepped pulley 10. Thepulley 10 is connected by a driving belt 11 to a correspond ing butoppositely positioned pulley 12, and said last named pulley is securedto a countershaft 13 arranged parallel to the main 1 driving shaft 1 andextending into the base 5 where it is journaled in a housing 14 andprovided with a worm 15. The worm 15 meshes with a worm gear 16 which issecured. to a vertically disposed spindle 17 preferably mounted on athrust bearing 18 in the housing 14. ,The upper end of the spindle 17 isjournaied in a casting"1 9,.of which the; housing -14 preferably forms apart, -casting1 being supported on and securedtc the inwardly [extendingannular fiange' f 20r formed on the up er end of the base- The upperiend of the spindle 17 has secured to it a horizontally disposed spurpinion 21 which meshes with the interior teeth 22 of a ring 23 which isbolted or otherwise secured to a revoluble drum 24 which carries, thechucks and'their correlated devices, as will be hereinafter'more fullydescribed.

The drum 24 is mounted to rot-ate about a central vertical axis and-isformed with a vertically disposed, centrally positioned dust dischargingpassage 25 which leads into a dust collector -or trap 26, provided witha movable closure 27 and formed with a branch 28 to which there may besecured any desired form of suction device (not shown),

a screen 29 being secured in one end of the branch 28 so as to preventshell particles and dust from entering into the branch, compeL ling themto drop into the trap 26 from which they may be easily removed. Theupper end of the trap 26 is formed with an outwardly extending fiangt'so secured to the lower end of the casting 19, the hollow hub of thedrum 24, which'forms the discharge passage 25, having a scarfed jointwiththe upper edge of the trap. The passage 25 of the hub 24 leadsdownwardly from an upwardly projecting flared chamber 31 formed in thedrum, said chamber in turn communicating at its upper end with a seriesof ra' dially disposed and outwardly and upwardly projecting suctionmouths 32 that are formed in the drum and that open at the upper surfaceof a circular table 33 which forms the upper end of the drum, theentrance grids of said mouths 32 lying contiguous to the respectivechucks 34 which are designed to receive and holdthe button blanks whilethe same are being acted upon; In the present embodiment of the machine,there are twelve chucks arranged in a circular series around the marginof the table 33 at regular intervals, as best indicated in Fig; 2although it is to be understood-that our invention is not limited tothis or any. number of chucks.

disposed spindles 35 that are mounted to r0 tate about spindles beingsupported at their lower ends their longitudinal axes, said,

in vertically movable step bearings 36 which are provided at their lowerends with rollers 37 mounted to travel on a cam track 38, said cam trackbeing supported between the flange of the "casting 19 and the flangewhich is formed at the lower end of the cylindrical'upper casingsection5, and being so formed that the spindles with the'chucks in them will bemoved upwardly to present the blanks in the-spindles to the devices thatwork upon the blanks, as will'be hereinafter more specificallydescribed.

By reference to Figs. 1 and 7 it will be understood that the shanks areformed on thefblanks by grinding, in-the present embodiment of theinvention, this operation being performed in the present instance by:means of. a grinding disk 39 secured to a vertically. disposed shaft 46mounted in a bracket 41 and which the driving belt 43 passes. alsopasses over idlers 44 and around a pulley'45 which is secured to themain driving shaft 1. The bracket 41 is mounted for vertical movementona guideway 46 so that the position of the disk 39 may be' adjustedvertically,- asrequired, and the guide-way 46 is in turn adjustable inthe standard or post 3, being securedat its rear side'to a rod 47 whichis inturn fastened to a slide 48. mounted-on abracket 49 and operated byahand wheel -50, the horizontal adjustment of the disk 39 beingt-herebyattainable. The chuck spindles 35am rotated as they are carrying apulley raised into operative relation to' the grind- 42 over I This beltnewness ing disk 39 as" the spindles aire carried around by the table33. ":To eflect the rota I tion ofthe' -s indies, each of them carriesa. pulley51 esigned' in a portion of the traverse ofthe-table 33: to beengaged'by a circumferent-i'ally extending stretch '52- of a pulley-56which is carriedby-a -vertically-disposed-.-shai'=t- ,57 journaledin thespindle '3;

Thus,the blanks will be treated one after the other, in their turn. and lliecompleted blankor button will pass on, in the continued revolution ofthe table 33, to the discharge point where, for iu- 5 stance, it may besucked out of theopencd chuck by means of a suctiontubc, as indi'.cziled at 106 in Fig. 2.

it is, of course, to be understood that the chucks mustbe givenacne-half revolution about their axes of rotation between the time thefirst milled. out portioirof the shank is formedand the time thenextinilled out portion is to be formed. T o accomplish this, we haveprovided the bracket 83 with downwardly projecting portions 107, one ofwhich is formed with the inwardly turned lower end 108 carrying twospaced. rollers 109, designed for engagement, successively, with thekeepers 61, in the recesses 62 thereof. It will thus be understood thatafter the tool '88 has acted upon a blank, the arm 69 is swungrearwardly relative to the direclio'n of rotation of the table 38 adistance equal to the space between two blanks or chucks, and that inthis movement the ad: joining latch arm 63 will be disenga g'ed' fromits corresponding keeper 61 by 'acam 110, while the two rollers 109 willsuccessively engage the recesses 62 in two adjoining faces oft-he'keeper and impart a halfturn to. thekceper, whereupon the latchwill ride off of the cam 110 and again engage the keeper so as to holdthe chuck stationary in reversed position, as regiu'ds the blank, sothat rho succeeding inward movement of the tool $9 will mill out theopposite side of the shr nk as the bracket 83 is again carried forwardwith the table 33 for a shortdistance. The next reverse movement of thebracket 83 will carry the blank, here used as an example, and thedrilling tool90, in operm tire relations with each other, whereupon thecam 102 operating upon the shaft 9101? the drilling tool, will force thelatter inwardly to pierce the shank and complete the formation of thethread-receiving opening.

Each of the arms 107 carries'upper and lower guide rollers 111 designedto engage the upper and lower faces of the table 33 at the rim thereof,for guiding purposes, and each rim is preferably provided with an car112 in which an adjusting screw 113 works, said screw bearing upon aslide 70 which directly carries therotz ting part above it, whereby'thevertical positions of the shafts 91 may be-varied so as to bring thetools which they carry into the proper plene for co-action with theblanks.

From the foregoing description in connec- ,machine will be apparent.

he present emhodimentpf the invention,

so far as the milling anddrilling operations are concerned, is of suchcharacter as to workon three blanks at once, the operation being apractically.continuous one so far as the formation of the completedarticles is concerned, the milling and drilling tools moving with thechuck carrier as they operate upon the blanks, and then moving back. onestep to catch up with the nextblank in the series, so as torepcat-theiroperations} By first milling the shanks as hereinbefore described, thedrill will be properly centered as regards the shank, andall-liabilityof the drill slippingfrom" the shank or the .blank slippingfrom the drill avoided, while at the same time the milling out of the"shanks on opposite sides manifestly facilitates the subsequent drillingoperation and tends to a considerable degree to avoid the liability ofbreaking the but-tons.

While the accompanying drawings disclose what we believe to be thepreferred embodiment of our invention as regards the. machine arrangedfor forming buttons of the self shank type, it is to be understoodthatthe invention-is not liniited thereto, but hat various-changes.may-be made in the construction, arrangement and proportions of theparts within the scope of the claims.
